Prosecutors may charge two ex-aides of ruling party kingpin Ichiro Ozawa without arrest for allegedly failing to list more than ¥400 million in his funds management body's 2004 political funds report, sources said Jan. 8.

The two are Lower House member Tomohiro Ishikawa, 36, of the ruling Democratic Party of Japan, and Takanori Okubo, 48, a former state-funded secretary to Ozawa.

Both are expected to be indicted on charges of violating the Political Funds Control Law for allegedly failing to list the funds involved in the political funds report.

The funds involved were more than ¥400 million, which was used to purchase a tract of land in Tokyo in October 2004 to build a dormitory for Ozawa's secretaries.

Ishikawa, who oversaw clerical work at Ozawa's funds management body, Rikuzankai, at that time, is suspected of having briefed Okubo, who was Rikuzankai's chief accountant and performed the body's accounting work in detail.
